He had no points or penalty minutes in his brief SuperElit experience. In 35 games for Huddinge IK U18 he had 10 assists and was plus-seven with 16 penalty minutes.

Fernholm was plus-one with 2 assists in three games for Team Sweden at the Four Nations tournament. He skated in seven games (including two playoff contests) for Huddinge's U18 team and was minus-one with 2 assists. Ranked 32nd amongst European skaters in Central Scouting's final rankings, Fernholm was selected by Nashville in the sixth round (164th overall) of the 2012 NHL Draft.
2012-13: Fernholm opened the season in the SHL with Frolunda — appearing in five games as an 18-year-old before returning to the club's U20 team. He had one point (an assist in his first game against AIK) and was +1 averaging just over 2 minutes of ice time. In 41 games for Frolunda's U20 team he had 10 assists and was +30 with 10 penalty minutes. Frolunda finished first in the regular season and was fourth after falling to Farjestads in the bronze medal game. Fernholm was +2 with 1 assist and 2 penalty minutes in four playoff games. He also skated in six games for Sweden's U20 team and was +1 with no points nor penalty minutes but did not compete in the World Junior Championship.
Fernholm is a big stay-at-home defenseman that has long reach and plays a very sound game in his own zone. His hockey IQ and hockey sense are very high which allows him to be extremely poised under pressure and he has a really good first pass. He is not very spectacular because he just makes the simple and easy plays when in trouble. The big defender is pretty mobile for his size but needs to work on his reverse pivots and skating balance. The young blueliner has to get stronger and heavier to use size advantage in order to play a more physical game.
Big defensive defenseman are always a task to develop, and Fernholm has been doing his best in the junior level of Sweden with Frölunda. Speed is obviously going to be the biggest step for the 6’4 Swede, and as he moves up to the SHL, the AHL, and potentially the NHL, he will have to adjust to increased speed. Realistically he is still several years off as that transition does not happen quickly normally.
